Mr. Going-to-do

Every Saturday John talks to Mr. Smith. He always says he is going to do something. "I'm going to clean my house today." he says, or" I'm going to wash my car tomorrow. "or" These trees in front of my house are too big. I'm going to cut them down next week. "Mr. Smith usually says, "Are you, John?" He knows his friend is not going to clean his house, or wash his car, or cut down any trees. Then he says, "Well, excuse me, John. I'm going to do some work in the house. "And he does.

Mr. Smith often says to his only child Dick. "Are you going to do something? Then do it! Don't be another Mr. Going-to-do."
